Title: Cleaning method and system using a solvent
Inventor: TANAKA MASATO
IPC: B08B3/12
Filed: 1990-06-21
Granted: 1999-08-03
Abstract: A cleaning method and cleaning system using an organic solvent such as Freon.   A cleaning tank (1) is closed  after  an article  (2)  to  be cleaned  is  placed within the cleaning tank.   The cleaning tank (1) has a downwardly concave bottom wall  (60)  carrying ultrasonic oscillators  (11).    The  solvent  is  supplied  to  the cleaning tank (1) from a solvent storage tank (3).   The article is cleaned with the supplied solvent.  After the cleaning, the solvent is discharged in liquid state from the cleaning tank (1) while vapor of the solvent which remains in the cleaning tank is discharged to a condenser (16)  to condense the vapor.   The condensed solvent is returned from the condenser (16) into the solvent storage tank (3).  After the liquid solvent and vapor solvent are discharged  from  the  cleaning  tank  (1),  the  cleaned article is taken out from the cleaning tank.  Before the cleaned article is taken out, air is introduced into the cleaning tank (1) at least at a last part of the step of discharging the vapor of the solvent.  The condenser (16) is incorporated in a distiller  (14).   A solvent vapor supplying unit  (34)  is connected to the cleaning tank (1).  The thus provided closed system prevents release of Freon to the atmosphere.

Title: Optimization of cyclic steam in a reservoir with inactive bottom water
Inventor: ALAMEDDINE BASSEM R
IPC: E21B33/138
Filed: 1990-09-27
Granted: 1997-11-18
Abstract: A process for preventing steam entry into a bottom water zone of a formation.  Perforations are made in a well which perforations communicate with the lowest level of said bottom water zone.  Air is injected into the lowest level of said zone via said well which initiates low temperature oxidizing thereby increasing the viscosity of said oil and making a heavy oil.  When a desired viscosity is obtained, air injection is ceased.  Said well is recompleted and perforations are placed in said well which causes it to communicate with a higher level oil saturated zone.  Steam is injected into said higher level since the lowest level of the bottom water zone is closed because of the high viscosity oxidized oil.  Thus, steam injection causes oil to be removed from the higher level of said formation.

Inventor: NELSON JOSEPH MADISON
IPC: E21B43/08
Filed: 1990-12-12
Granted: 2000-02-01
Abstract: Disclosed is in situ decontamination methods and apparatus for injecting a hot gas into boreholes formed in a contaminated soil area to vaporize the soil moisture and contaminants, and for collecting the vaporized contaminants at the surface of the soil. A burner heats pressurized gases and mixes the same with combustion gases for injection into the contaminated zone. A central collection system recovers the vaporized contaminants and couples such vapors to an on-site incinerator for disposal. Controlled heating of the injection gas is effective to sequentially remove different types of contaminants, as well as to provide in situ oxidation of other contaminants, while minimizing recondensation of the soil vapors. Wellbore casings are especially adapted for injecting the gas in predetermined patterns. In addition, a heater and incinerator assembly utilizes a single burner for both heating the dry gas and for incinerating.the vapor contaminants.

Title: Network control arrangement
Inventor: CLOONAN THOMAS J
IPC: H04B10/27
Filed: 1992-01-29
Granted: 1994-10-04
Abstract: NETWORK CONTROL ARRANGEMENT Abstract A network arrangement and control method where, before any transmission of data occurs for a particular communication, a network controllerdetermines an unused path to provide a connection, advantageously all the way through the network from a given inlet to a given outlet. Once the identity of the unused path is known, the controller determines control information for use in activating that path and transmits that control information into the network, significantly via the network inlets. The network responds by activating the determined path and communication is enabled via the activated path, but only for the single connection and no buffering of information is required within the network. The network is particularly well suited for optical implementation and control is effected without the use of spatial light modulators but rather by means of control elements embedded within the network itself.

Abstract: The present invention relates to a method and apparatus for treating pulp, which method and apparatus are especially suitable for treating fiber suspensions in wood processing industry. The method and apparatus are particularly designed for thickening said suspensions, in other words filtering liquids from fiber suspensions in pulp and paper industry. The invention relates more closely to a so called drum cylinder, the basic construction of which comprises a vessel, into which suspension being thickened is supplied and a wire-surfaced cylinder rotating in the vessel. The drum filter in accordance with the present invention is characterized in that the closing member (40) of the drum filter has a channel (70) for leading gas from the filtrate tubes (24) through the compartments of the distribution chamber (26) to the outside of the closing member (40). The method in accordance with the present invention is characterized in that the operation phase of the filter cylinder is divided into five stages separated from each other, in the first stage, when the cylinder descends into the vessel, air and the initial filtrate are discharged from the filtrate compartments and the formation of the pulp web on the wire surface begins; in the second stage filtrate is discharged with vacuum and the formation of the pulp web continues; in the third stage pulp web is dried by means of vacuum when said part of the web has risen with the cylinder from the vessel; in the fourth stage, a so called removal stage, pulp web is removed from the wire surface and discharged from the apparatus; and in the fifth stage, a so called washing stage, the wire surface is washed.
